VSat Antennas

VSat | Antennas

A new line of maritime antennas for satellite communication through a Very-small-aperture terminal (VSAT) on vessels at sea was developed by Pasquali Microwave Systems in collaboration with Navisystem Marine Electronics (http://www.navisystem.com), worldwide leading company in the production of marine satellite antennas.

The latest VSAT Antennas are the outcome of a research project partially funded by Regione Toscana in the framework of POR CReO FESR 2007-2013 European Funding for Regional Development (link: http://www.regione.toscana.it/creo), the segment intended for supporting investments in industrial research and experimental development.

The newly developed maritime VSAT Antennas are:

VSAT-60 Ku

VSAT-95 Ku

VSAT-115 Ku

VSAT-240 C

VSAT-60_Ka

VSATantennas were designed and experimentally optimized in order that RF performance meets Eutelsat (http://www.eutelsat.com) standards for VSAT terminal ESV(Earth Station on Vessels). European leader satellite company.
The procedure of antennas characterization and validation to obtain Eutelsat type-approval according to Eutelsat Earth Station StandardM (EESS 502) is currently in progress.

RF Components for maritime VSAT antennas:

OMT

Orthomode transducer: component in the RF chain that serves to separate the two orthogonal Rx and Tx signals.
The new PMS OMTs specifically designed for maritime VSAT antennas are:

It is employed in VSAT terminals that operate in circular polarization.
PMS developed two novel iris polarizer with optimized Tx Axial Ratio performance:

Ka-band waveguide polarizer (included in VSAT60-Ka antenna)

Ka-band waveguide polarizer (included in VSAT60-Ka antenna)

VSAT 62

VSAT 240
